| Outline of Final Research Achievements |
The improvement of the durability of porous concretes is successfully achieved by applying the reinforcement with vinylon short- and micro-fibers and the binder modification with cement modifier. The better correlation between the durability and mechanical properties is recognized for the ordinary cement concrete. The relationships between the static modulus of elasticity, dynamic modulus of elasticity and compressive strength of the porous concretes are clarified for the performance design. The equation for estimating the static modulus of elasticity of the porous concretes is proposed by applying the law of mixture introducing the correction coefficient of the voids.
